Advfs is Digital's Advanced File System.  It is fundamentally different 
type of file system than UFS.  Originally, it saw light of the day with 
OSF/1 (renamed to Digital UNIX, and than (insert current company name) 
Tru64 UNIX).  You'd usually see it on Alpha boxes.  Apart from being 
very fast file system, it also included LVM, and could be used as file 
system for clusters (don't remember anymore, but I don't think ufs was 
supported fs type for Alpha clusters).

Digital had a great chip (Alpha), and good OS (Tru64) to run on it.  But 
in this world, it is not enough to have technically superb product (in 
comparation, Intel is now starting to get where Digital was some 5-10 
years back).  You need to have a company to back it up.  Digital (a 
company that did some really awsome development) was such an company. 
Compaq (a PC parts assembly company, zero development) wasn't.  HP has 
its own (inferior) line of UNIX workstations/servers to support.
